Edwards Vacuum

XDS scroll pumps have become industry standard when dry pumping is essential, proving to be a robust and clean vacuum pump solution in a range of applications and processes. The XDS35i pump has an innovative bearing shield that isolates the vacuum environment from all forms of lubricant, making it not only lubricant-free but hermetically sealed. XDS35iNGB variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery.The XDS46i shares many of the same features of the XDS35i but with a peak speed of 40 m3h-1. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it ideally suited for LCMS and ICPMS applications requiring higher pumping speeds. The C variant has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications using corrosive substances. The C version is fitted with Chemraz® internal valve pads and stainless steel exhaust port.Chemraz® is a registered trademark of Greene Tweed.

In summary, you can rest assured that when you choose an Edwards RV oil sealed rotary vane pump you are choosing a product you can rely on from a company you can trust. The success has been based on field proven design and reliability in a wide range of applications and environments. High Vapor Handling: Quicker Process Superior Particulate Handling: High Reliability Fast Acting, Dependable Inlet Valve for Anti-Suck Back Protection: Safe Process & Systems Mode Selector & Two Position Gas Ballast: Configured to Meet Your Vacuum Needs Designed for Easy Maintenance: No Unplanned Downtime Quiet Running: Better Work Environment Analytical instruments – LCMS Distillation Extraction Filtration Freeze drying Gel drying Solvent recovery Centrifugal evaporation DUSTY APPLICATIONS Furnaces De-gassing CLEAN DRY APPLICATIONS Analytical instruments – GCMS Centrifuges Coating Turbo pump backing Gas bottle filling/emptying Leak detectors Load locks Electron microscopes SPECIAL APPLICATIONS Where your application does not fall into one of the other categories, we can offer pumps specifically designed to meet your requirements. Past examples of these include: PFPE prepared pumps Versions compatible with brake fluid ATEX approved pumps Air driven motor variants for oil and gas rig Many of these variants have gone on to become standard catalogue items, so if you have an unusual application please ask your local salesman and we will be pleased to help KEY FEATURES AND BENEFITS OF THE Edwards RV3 WET PUMPING Key benefits of Edwards RV3 pumps for “wet” applications: Highest vapor pumping capacity of any rotary vane pump Unique mode selector switch means pump maintains lubrication at high flow Highest gas ballast flow of any rotary vane pump giving 220g/hr (290g/hr on RV12) water vapor handling capacity Optional oil return kit to ensure the oil stays in the pump at high flow For applications where the solvents/vapors are incompatible with fluoroelastomer (FKM) seals, a nitrile (Buna-N) conversion kit is available. Additionally PFPE prepared pumps may be ordered if pumping large quantities of oxidants. DUSTY Key benefits of Edwards RV3 pumps for “dusty” applications Best in class anti-suck back protection to prevent dust getting back into the process Controlled opening by oil pressure to eliminate pressure surge Rapid closing within 0.4 seconds of pump stopping due to dump valve Large diameter oil passages (3-5mm) to avoid clogging Some competitor pumps have oil passages of less than 1mm diameter Designed using experience of PVD and CVD applications from the semiconductor industry, Edwards range of RV pumps are ideal for dusty applications. CLEAN/DRY Key benefits of Edwards RV3 pumps for clean/dry applications Unique mode selector switch means pump maintains lubrication at high flow Optional oil return kit to ensure the oil stays in the pump at high flow Best in class anti-suck back protection to prevent oil mist getting back into the process Controlled opening by oil pressure to eliminate pressure surge Rapid closing within 0.4 seconds of pump stopping due to dump valve The patented mode selector means that the pump is equally happy in either high vacuum applications or high throughput applications. For the latter an optional oil return kit can be fitted that allows the pump to operate continuously at high throughput without losing all its oil down the exhaust line. OXIDANTS Key benefits of Edwards RV3 pumps for pumping oxidants: Highest gas ballast of any rotary vane pump Allows dilution of pumped gases to minimize oxidation of the oil PFPE variants available Ideal for pumping oxygen and halogenated compound The high gas ballast of the RV pumps allows higher flows of oxygen whilst maintaining dilution to below the lower explosive limit. When combined with the optional oil return kit to prevent the gas ballast from blowing all the oil into the exhaust and a PFPE prepared pump to avoid oxidation of the oil, the RV pump makes a solid pump for oxygen. Equally these same features make the RV pumps ideal for pumping other oxidants such as halogens and halogenated compounds. For these compounds fire/explosion is not an issue, but a gas ballast is still useful for dilution to protect the oil and bearings. PFPE should be used to prolong oil life.

With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features, the nXDS dry scroll pump is the best performing pump in its class. nXDS improves on the original XDS pump technology by offering increased pumping speeds, combined with lower ultimate pressures, low power consumption and reduced noise. The gas ballast allows for pumping of condensable vapours, including water, solvents, dilute acids and bases. nXDS pumps feature the very latest in tip seal technology, giving a significantly longer life between tip seal changes. nXDS-C has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications involving corrosive substances. This chemically resistant version is fitted with Chemraz® internal valves and stainless steel fittings. nXDS-R has the gas ballast blanked off so it cannot be accidently opened. This is useful for applications such as rare gas recirculation or gas recovery.

The EXT75DX is a hybrid bearing compound turbo pump that combines the proven technology of a ceramic mechanical lower bearing, a dry permanent magnetic upper bearing and Holweck drag stage with the added convenience of an on-board 24V controller allowing parallel and serial communication compatible with our TAG and TIC controllers. It is available with either aDN40NW, ISO63, DN63CF or an ISO100 inlet flange with an N2 pumping speed of up to 66ls-1. A basic pump system would require an EXT75DX pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing pump.

Edwards Swing Clamp, KF-25 (NW-25), Polymer, C10514304

Overview:
The Clamping Ring is used to connect vacuum plumbing and process systems in combination with vacuum pumps or vacuum components.This swing clamp is used in conjunction with a centering ring with a fitted O-ring for mating KF flanges.The Swing Clamps are available in the following sizes: NW 10/16, NW 25, NW 32/40, NW 50.KF (also referred to as NW) assemblies consist of two Flanges, a Center-Ring and a Clamp. A uniform application of pressure on the clamp insures a vacuum seal. The mating flange surfaces compress the O-Ring, which is held in place by a centering ring, to generate the vacuum seal.
